BACKGROUND Field

Advancements in peripheral device and central device interoperation user experience are needed to provide improvements in cost, profitability, performance, efficiency, and utility of use.

Unless expressly identified as being publicly or well known, mention herein of techniques and concepts, including for context, definitions, or comparison purposes, should not be construed as an admission that such techniques and concepts are previously publicly known or otherwise part of the prior art. All references cited herein (if any), including patents, patent applications, and publications, are hereby incorporated by reference in their entireties, whether specifically incorporated or not, for all purposes.

Improvements to peripheral device and central device interoperation user experience are needed to ease transition from classic-energy radio technology to low-energy radio technology. Examples of a central device are a smartphone, a tablet computer, a laptop computer, and any other type of device usable in conjunction with a peripheral device. Examples of peripheral devices are a Near Field Communication (NFC) tag reader and/or writer, a Radio Frequency IDentification (RFID) reader and/or writer, a barcode (e.g. optical barcode) scanner, and any other type of device usable in conjunction with a central device. An example of classic-energy radio technology is ‘classic’ Bluetooth (e.g. Bluetooth version 2.1). An example of low-energy radio technology is Bluetooth Low Energy (AKA Bluetooth LE, AKA BLE, e.g. Bluetooth version 4.2).

Under classic Bluetooth a peripheral that has previously been used with a central host is able to quickly and automatically reestablish a working link when the peripheral attempts to reconnect with the (ready and in range) central host, and without requiring any user direction to the central host. In contrast, under BLE the central has control over whether or not a working link is reestablished and the user must provide direction to the central host to reestablish a working link for a previously used peripheral. In this regard, the new BLE behavior has power management benefits, particularly in environments with many peripherals. However, users familiar with classic Bluetooth peripherals may be confused, delayed, interrupted, or otherwise inconvenienced by the different link reestablishment behavior when using BLE peripherals. The user may believe that the BLE peripheral is malfunctioning. Unwarranted returns or IT customer support calls may result. The user's efficiency and productivity may decline compared to use of classic Bluetooth peripherals.

SYNOPSIS

The invention may be implemented in numerous ways, e.g. as a process, an article of manufacture, an apparatus, a system, a composition of matter, and a computer readable medium such as a computer readable storage medium (e.g., media in an optical and/or magnetic mass storage device such as a disk, an integrated circuit having non-volatile storage such as flash storage), or a computer network wherein program instructions are sent over optical or electronic communication links. The Detailed Description provides an exposition of one or more embodiments of the invention that enable improvements in cost, profitability, performance, efficiency, and utility of use in the field identified above. The Detailed Description includes an Introduction to facilitate understanding of the remainder of the Detailed Description. The Introduction includes Example Embodiments of one or more of systems, methods, articles of manufacture, and computer readable media in accordance with concepts described herein. As is discussed in more detail in the Conclusions, the invention encompasses all possible modifications and variations within the scope of the issued claims.

Application-assisted friendly pairing provides a classic-energy radio technology user interface experience to a user operating a peripheral device in conjunction with a central device. The classic-energy radio technology user interface experience is provided while using a low-energy radio technology for communication between the peripheral device and the central device. The user interface experience is enabled via installation and execution of an application for friendly pairing (AKA friendly-pairing application) on the central device that hides from the user the different link reestablishment behavior of BLE peripherals, compared to classic Bluetooth peripherals. The friendly-pairing application enables a BLE peripheral that has previously been used with a central host to quickly and automatically reestablish a working link with the central host when both devices are next ready and in range of each other, and without manual user direction to the central host. By effectively emulating the classic Bluetooth link reestablishment behavior while using BLE, the friendly-pairing application effectively cedes control of BLE link reestablishment to the peripheral and in so doing mitigates user confusion, delays, interruptions, and other inconveniences, while providing compatible operation with both BLE and classic Bluetooth peripherals. The BLE peripheral interaction with the central host is as expected by the user familiar with classic Bluetooth peripherals. Unwarranted returns and IT customer support calls are thus avoided. A central and peripheral system compatible with both classic and BLE Bluetooth radio systems that uses the application-assisted friendly pairing thus works better and has improved process and operation over a system without application-assisted friendly pairing.

In some embodiments, Core MCU 2999 comprises one or more NVMs and the core is enabled to execute code stored in the NVMs.

FIG. 3 illustrates, via a flow perspective, embodiments for application-assisted friendly pairing. The flow perspective is that of a central role device executing an application for friendly pairing. An example of an operating context for FIG. 3 is the following. Management/Point-Of-Sale Tablet 1400 of FIG. 1 is, e.g., a phone operating as a BLE central device, and Radio-SS 1401 comprises a BLE radio. NRRW 1300 of FIG. 1 is, e.g., an NFC/RFID reader/writer operating as a BLE peripheral device, and Radio-SS 1320 comprises a BLE radio. The application-assisted friendly pairing, provided by a specific application referred to herein as ‘CaptureHelperUI’, enables a user to identify a specific instance of NRRW 1300 to a specific instance of Management/Point-Of-Sale Tablet 1400 as a known peripheral device. Once identified, the specific instance of Management/Point-Of-Sale Tablet 1400 recognizes the specific instance of NRRW 1300 with reduced delay compared to a system without the identification that the CaptureHelperUI provides.

Referring to FIG. 3, flow beings with the user installing the CaptureHelperUI application on Management/Point-Of-Sale Tablet 1400 (action 301). With the CaptureHelperUI application running in the foreground on Management/Point-Of-Sale Tablet 1400, the user indicates to the application to activate the favorite feature by providing specific input, such as by tapping/touching a particular portion of Display 1404 and/or activating one or more of Buttons 1405 (action 302). In response, the CaptureHelperUI application directs the BLE radio of Radio-SS 1401 to perform a BLE scan (action 303). The BLE radio of Radio-SS 1320 periodically provides advertising data that Radio-SS 1401 receives when NRRW 1300 and Management/Point-Of-Sale Tablet 1400 are within BLE radio communication range of each other. In response to reception of the advertising data, Management/Point-Of-Sale Tablet 1400 recognizes NRRW 1300 as a discoverable peripheral device (action 304).

The discoverable peripheral device is then marked (tagged, or otherwise identified) as a favorite by the CaptureHelperUI application (action 305). E.g., the user directs the application to do the marking, but more generally the marking is as detailed further below. The CaptureHelperUI application maintains state identifying current and/or past favorite peripheral devices in NVM, such as Nonvolatile storage 1406. The CaptureHelperUI application directs the BLE radio of Radio-SS 1401 to cease performing the BLE scan (action 306). Then the CaptureHelperUI application directs Management/Point-Of-Sale Tablet 1400 to implement a connection with NRRW 1300 as a favorite peripheral device (action 307). In some embodiments and/or usage scenarios, implementing the connection corresponding to a BLE peripheral being added as a favorite (flows reaching action 307 via action 305) comprises a connection, one-time pairing, and bonding, while implementing the connection corresponding to a previously identified BLE favorite (flows reaching action 307 via action 312) comprises connection and bonding. The connection is used (action 308) until either there is a disconnection event (for any reason) or the CaptureHelperUI application is reset (action 309).

If there is a disconnection event or the CaptureHelperUI application is reset, then the CaptureHelperUI application determines if there is a marked favorite (action 310). If there is not a marked favorite, then flow proceeds to action 303 to perform a BLE scan to attempt to discover a peripheral device. If there is a marked favorite, then flow proceeds to attempt to find the marked favorite by the CaptureHelperUI application directing the BLE radio of Radio-SS 1401 to perform a BLE scan (action 311). The CaptureHelperUI application determines if the marked favorite is found (action 312). If the marked favorite is found, then flow proceeds to action 306 to cease performing the BLE scan. If the marked favorite is not found, then flow loops as necessary through actions 312 and 313 to continue looking for the marked favorite. In some embodiments and/or usage scenarios, action 312 exits to, e.g., an error routine after a timeout period.

A disconnection event occurs variously, for example, when Management/Point-Of-Sale Tablet 1400 and NRRW 1300 move outside of communication range, either are turned off, or the user explicitly terminates the connection.

A reset of the CaptureHelperUI application occurs variously, for example, when the CaptureHelperUI application is (re)installed, the CaptureHelperUI application while running in the background is ‘swiped away’ (closed, or terminated), Management/Point-Of-Sale Tablet 1400 is turned off, or the user explicitly resets the CaptureHelperUI application.

In some embodiments and/or usage scenarios, action 303 comprises a BLE scan that limits resultant advertising data to peripheral devices that are of one or more particular types. For example, only NFC reader/writer peripheral devices are directed to respond. For another example, only RFID reader/writer peripheral devices made by a particular manufacturer are directed to respond.

In some embodiments and/or usage scenarios, a BLE scan request as sent by Management/Point-Of-Sale Tablet 1400 specifies a specific SERVICEUUID, and only peripheral devices that support the specific SERVICEUUID respond with advertising data. The advertising data is sufficient to determine that the respondents are eligible to be favorite peripheral devices, e.g., are of a proper type and/or made by a proper manufacturer.

In some embodiments and/or usage scenarios, action 304 results in discovery of a plurality of BLE peripheral devices. Optionally and/or selectively, only the first one of the plurality of BLE devices that is discovered is marked as a favorite peripheral device. Optionally and/or selectively, a representation of one or more of the plurality of discovered BLE peripheral devices are presented to the user, e.g., via Display 1404. In response, the user selects all or any portion of the presented devices as favorite peripheral devices, e.g., by tapping/touching Display 1404.

The CaptureHelperUI application enables the unified management of various diverse peripherals. In some embodiments and/or usage scenarios, there are a plurality of favorite peripheral devices, and connections are implemented with all or any portion of the plurality of favorite peripheral devices as they are discovered (e.g. actions 311 and 312). In some embodiments and/or usage scenarios, the connected favorite devices comprise one or more devices selected from a) NFC reader/writers, b) RFID reader/writers, and c) barcode readers. In some embodiments and/or usage scenarios, the CaptureHelperUI application enables the display of scanned data from any of the connected device types. In some embodiments and/or usage scenarios, the CaptureHelperUI application manages the automatic reconnection of any favorite device, disconnected for any reason.

In some embodiments and/or usage scenarios, the CaptureHelperUI application implements the add to favorites function based on the state of a GUI rendered virtual switch on the central's touch screen.

In various embodiments and/or usage scenarios, the CaptureHelperUI application is executed in whole or in part by Processor 1420. In various embodiments and/or usage scenarios, the CaptureHelperUI application maintains state identifying current and/or past favorite peripheral devices in Non-Volatile Memory (NVM), such NV Storage 1406.

FIG. 4 illustrates, via a flow perspective, additional embodiments for application-assisted friendly pairing. The flow perspective is that of a central role device executing an application for friendly pairing. With respect to the discussion of FIG. 4, it will be understood that adding favorites means adding new peripherals to the set of peripherals marked as favorites, and otherwise the term favorites refers to marked favorites (devices previously identified as favorites). It will further be understood that available means powered on with an appropriate radio in range and ready to connect. Aspects not detailed below explicitly with respect to FIG. 4 are as otherwise described in conjunction with FIG. 3. As a prerequisite activity, the user installs the CaptureHelperUI application on Management/Point-Of-Sale Tablet 1400 (action 401).

Once installed and executing, the CaptureHelperUI application's pairing assist functionality begins (or resumes after a predetermined special event, discussed below) at action 402. While FIG. 4 shows flow proceeding from action 402 to action 410, it will be understood that flow could instead equivalently proceed from action 402 to action 412.

If at action 410 favorites are to be added (e.g., as directed by a user), then flow proceeds to action 404 to (re)connect with all available but currently disconnected peripheral devices. (Any existing connections are maintained without interruption.) According to embodiment and/or usage scenarios, the CaptureHelperUI application decides whether to implement the add to favorites function based on the state of, or state transition of, a GUI rendered virtual switch on the central's touch screen. E.g., toggling or tapping (clicking) the virtual switch is treated as user input to add new favorites (Yes, exiting action 410 to the left).

In some embodiments and/or usage scenarios, the add favorites mechanism connects all available peripherals regardless of their favorite status/history. In some embodiments and/or usage scenarios, implementing a connection at action 404 corresponding to establishing a new BLE favorite comprises a connection, one-time pairing, and bonding, while implementing a connection at action 404 corresponding to a previously established BLE favorite comprises connection and bonding.

Any first-time connected peripherals are marked as favorites (action 405) and remain as such unless explicitly removed under user input. The connection is used (action 408) until there is a predetermined special event (action 409), such as a disconnection event (for any reason), the CaptureHelperUI application is reset, one or more special interrupts has happened, or one or more polling intervals or other timers has lapsed. The next time that a newly marked favorite peripheral is power cycled, or is otherwise disconnected for any reason, upon again becoming available the peripheral will automatically reconnect with the central (as the central has the peripheral identified as a favorite).

If at action 410, currently no favorites are to be added, then the flow next determines if one or more favorites are available (action 412). If favorites are available, then flow proceeds to action 407 to (re)connect with all available but currently disconnected favorites. (Any existing connections are maintained without interruption.) In some embodiments and/or usage scenarios, implementing the connection corresponding to a favorite (action 407) comprises connection and bonding. Flow then proceeds to action 408 as described previously. If favorites are not available (action 412), then flow proceeds back to await adding new favorites (action 410).

FIG. 5 illustrates, via a state perspective, additional embodiments for application-assisted friendly pairing. The state perspective (with a few exceptions to be detailed below) is that of a peripheral role device interacting with a central role device (AKA, the central) executing an application for friendly pairing. With respect to the discussion of FIG. 5, it will be understood that the term favorite refers to a peripheral that is marked favorite (a peripheral previously identified as a favorite). Aspects not detailed below explicitly with respect to FIG. 5 are as otherwise described in conjunction with FIGS. 3 and 4.

The peripheral device operation begins in Off/Reset state 510. If the peripheral is powered (condition Power Up, 512), the peripheral becomes available to the central (Available state 520) once the peripheral's radio is ready and in range. As detailed further below, depending on various conditions, the peripheral may transition to another state as described below, or otherwise continue in Available state 520 indefinitely (Not (Is Favorite OR Add OR Special Event), condition 523).

If an add favorites operation is performed on the central (condition “Add”, 522), the peripheral becomes connected to the central ((Re)Connect state 550), is marked as a favorite on the central (Become Favorite, state 560), and is used by the central (Use, state 540). In some embodiments and/or usage scenarios, the add favorites mechanism connects all available peripherals regardless of their favorite status/history. In some embodiments and/or usage scenarios, implementing (Re)Connect state 550 corresponding to establishing a new BLE favorite comprises a connection, one-time pairing, and bonding, while implementing (Re)Connect state 550 corresponding to a previously established BLE favorite comprises connection and bonding.

If the peripheral has previously been marked as a favorite (condition Is Favorite, 521), the peripheral is reconnected to the central (Reconnect, state 530), and is used by the central (Use, state 540). In some embodiments and/or usage scenarios, implementing the connection (Reconnect state 530) corresponding to a previously established BLE favorite comprises connection and bonding.

The peripheral may continue indefinitely in Use state 540 (Continue Use, condition 541), until a predetermined Special Event, condition 513, such as a disconnection event (for any reason), or the peripheral is reset or powered off. Upon Special Event, condition 513, the peripheral will transition, from either the Use state 540 or the Available state 520, back to the Off/Reset state 510.

Some cross-references to FIG. 4 are as follows. States 550 and 530 correspond respectively to actions 404 and 407. The peripheral itself is unaware of Become Favorite, state 560, which corresponds to an action in the central (e.g. action 405 of FIG. 4). Use state 540 corresponds to action 408.
